Sommer–Rathbun–Battles syndrome is an extremely rare condition first described in 1974 in two siblings. Doctors noticed three main things together: (1) eye changes with partial aniridia (the colored part of the eye—the iris—was under-developed), sometimes with congenital glaucoma and telecanthus (wide inner eye corners); (2) one kidney missing (unilateral renal agenesis); and (3) mild psychomotor delay (slower development of movement and skills). Since that first description, no additional well-documented cases have been published, so medical knowledge about this syndrome is very limited. Qeios+3PubMed+3Genetic Diseases Info Center+3
This name was given to two siblings described in 1974 who had: partial aniridia (iris underdevelopment), congenital glaucoma, telecanthus (wide-set inner eye corners with normal pupils), a characteristic facial look (frontal bossing, hypertelorism), unilateral renal agenesis (one kidney missing), and mild psychomotor delay. Later summaries use the label Aniridia–renal agenesis–psychomotor retardation (ARAPR) and remark on its extreme rarity—with no further case descriptions since 1974. PubMed+2Genetic Diseases Info Center+2
Most registries list ARAPR as extremely rare and possibly autosomal recessive (based on the sib pair), but no causative gene has been proven. Because aniridia is commonly due to PAX6 in many other settings, some readers assume a PAX6 link—but that has not been shown for ARAPR itself. Clinicians therefore manage each component on its own merits. Genetic Diseases Info Center+1
Because only two people have been reported, doctors cannot yet define the exact cause or a full symptom range. Orphanet lists inheritance as autosomal recessive (both parents likely carry one silent change), but the specific gene is unknown. Prevalence is estimated at <1 per 1,000,000. Orpha+2MalaCards+2
Other names
Doctors and databases also call this condition by these names:
Aniridia–renal agenesis–psychomotor retardation syndrome.
Sommer–Rathbun–Battles syndrome (named after the authors of the 1974 report).
Occasionally you may see “aniridia–ataxia–renal agenesis–psychomotor retardation” on summary pages, but “ataxia” was not part of the original, two-sibling description; it appears in some compilations and needs caution. Genetic Diseases Info Center+2PubMed+2
Types
There are no recognized subtypes or “types.” All reliable sources describe the same core picture from the single family reported in 1974. Later databases repeat that summary and note that no further cases have been published. In practice, clinicians may describe variant features (for example, how much of the iris is missing or which kidney is absent), but these are not formal types. Genetic Diseases Info Center+1
Causes
Important context. The actual cause of SRB syndrome is unknown. Because the triad is unusual, doctors look for other, better-understood genetic conditions that can mimic parts of it (eye + kidney + developmental features). The items below are not proven causes of SRB syndrome itself; they are look-alike conditions and gene pathways doctors check to exclude before labeling a case as SRB. I’ll note the key reason each is considered.
Unknown autosomal-recessive gene (primary hypothesis). Orphanet reports presumed autosomal-recessive inheritance based on the sibling pair; no gene has been identified. Orpha
11p13 deletion (WAGR syndrome: PAX6 + WT1). This causes aniridia plus genitourinary anomalies and developmental issues; clinicians first exclude this with chromosome microarray/FISH because it is much more common than SRB. NCBI+2Frontiers+2
PAX6 sequence variants (classic aniridia without WT1 loss). Most aniridia is due to PAX6 haploinsufficiency; this explains the iris problem but not usually renal agenesis, so it is part of the differential work-up. JCI Insight+1
ITPR1 variants (Gillespie syndrome). Causes aniridia with ataxia and intellectual disability; kidney defects are not typical, but Gillespie can be mistaken for “aniridia with developmental delay,” so genetic testing often includes ITPR1. PubMed+1
FOXC1 mutations (anterior segment dysgenesis). FOXC1 affects development of the eye’s front structures and can come with systemic features (including occasional renal anomalies), so it is checked when aniridia-like changes plus other anomalies are present. PMC+1
PITX2 mutations (Axenfeld–Rieger spectrum). Another anterior-segment gene; ocular changes + diverse systemic anomalies make PITX2 part of panel testing. Nature
HNF1B haploinsufficiency (17q12 microdeletion or intragenic variant). A common monogenic cause of developmental kidney disease with possible neurodevelopmental issues; considered when renal anomalies dominate. PMC+2ScienceDirect+2
PAX2 variants. Well-known kidney-development gene; sometimes associated with renal agenesis/hypodysplasia; included to explain the renal side of the triad. PMC+1
EYA1 (BOR syndrome) and SIX1. Classic branchio-oto-renal genes; they explain renal anomalies and (less commonly) ocular anterior-segment changes; considered in CAKUT panels. Lippincott Journals+1
SALL1 (Townes–Brocks syndrome). Causes renal malformations among multi-system findings; checked in broad CAKUT gene panels. PMC
FRAS1 / FREM2 / GRIP1 (Fraser syndrome genes). Fraser can include cryptophthalmos/microphthalmia and renal agenesis; severe eye involvement can be confused with “aniridia-like” appearance in summaries. Nature+2ScienceDirect+2
RET / GDNF pathway defects. Core signaling for ureteric bud induction; disruptions can lead to renal agenesis, so these pathways are relevant in the genetic search for a unifying cause. PMC
PBX1. Recognized CAKUT gene; variants can cause wide renal malformations and are part of modern sequencing panels. Wiley Online Library
BMP7 / WNT4 / WNT11. Kidney morphogenesis factors; included because of their role in renal development and CAKUT. PMC+1
WT1 sequence variants (e.g., Denys–Drash/Frasier spectrum). WT1 explains GU and renal disease (not aniridia), so it is assessed when kidney findings are prominent. ClinGen
FOXC1/PITX2 copy-number changes (6p25/4q25). Larger deletions/duplications around these genes can produce ocular anterior-segment anomalies with extra-ocular features, sometimes including renal involvement. Nature
COL4A1/related small-vessel genes (selected cases). Certain ocular + brain anomalies with developmental delay may bring these genes into the differential when imaging suggests vascular/white-matter changes. (Broader ASD/neurology reviews discuss this overlap.) Cell
Chromosomal copy-number variants (CNVs) outside 11p13. Clinical microarray can detect pathogenic deletions/duplications explaining mixed eye–kidney–neurodevelopmental findings. ClinGen
Regulatory region defects around PAX6. Deletions outside the PAX6 coding region can still cause aniridia; considered when coding tests are negative. SpringerLink
Multifactorial/unknown developmental field defect. When all targeted tests are negative, clinicians may conclude the child has a unique, unsolved developmental syndrome, which is where the historic SRB label has been used. Genetic Diseases Info Center
Symptoms and clinical features
Note: With only two reported patients, we rely on the original 1974 description and standard effects of the listed abnormalities. Not every person would have every feature.
Partial aniridia. The colored iris is under-developed, so the pupil can look very large. Light can be harsh and focusing can be poor. Genetic Diseases Info Center
Photophobia (light sensitivity). Less iris tissue means too much light reaches the retina, causing discomfort in bright settings. (General aniridia effect.) JCI Insight
Reduced visual acuity. Vision may be blurry from iris hypoplasia and often from foveal under-development that commonly accompanies aniridia. JCI Insight
Nystagmus. Eyes may make small, rapid movements because the visual system did not develop fully early on. (Common in aniridia.) JCI Insight
Strabismus (eye misalignment). The eyes may not point in the same direction; this is also common in aniridia. JCI Insight
Telecanthus. The inner corners of the eyes are wider apart than usual, giving a “wide-spaced” look to the inner eyelids. Genetic Diseases Info Center
Hypertelorism. The eye sockets themselves can be farther apart than average. This contributes to facial appearance. Genetic Diseases Info Center
Frontal bossing. The forehead looks prominent. It is a facial shape difference reported in the original summary. Genetic Diseases Info Center
Congenital glaucoma (in some). Pressure inside the eyes can be high at birth, which can harm the optic nerve if untreated. Genetic Diseases Info Center
Unilateral renal agenesis (one kidney absent). Often there are no symptoms early on, but long-term there is less “reserve” kidney tissue. Genetic Diseases Info Center
Mild psychomotor delay. Babies may sit, crawl, or walk later than average; fine motor and problem-solving skills may develop more slowly. Genetic Diseases Info Center
Speech and language delay (variable). Many children with general psychomotor delay also speak later; this was not detailed in the 1974 letter but fits the overall developmental profile.
Poor visual-motor coordination. Eye conditions plus developmental delay can make hand–eye tasks harder.
Head-turning or “null point” posture. Some people with nystagmus turn the head slightly to find a position where eye movement is calmer.
Feeding or growth concerns in infancy (rare/indirect). Developmental delay and visual issues can indirectly affect early feeding and growth in some children with complex congenital syndromes. Genetic Diseases Info Center
Diagnostic tests
Why test? Because SRB is so rare and unsolved, the real-world goal is to describe the child’s features precisely, protect vision and kidney function, and exclude more common genetic syndromes (like WAGR, PAX6-related aniridia, HNF1B-related disease, Gillespie, Fraser). The tests below are standard for these aims.
A) Physical examination
Complete dysmorphology exam. A clinical geneticist examines facial shape (forehead, inter-canthal distance), limbs, skin, and other organs to spot patterns that point to a known syndrome. Genetic Diseases Info Center
Focused eye exam in the clinic. Look for iris hypoplasia, pupil shape, cornea clarity, and signs of glaucoma (enlarged cornea, tearing). (General aniridia practice.) JCI Insight
Blood pressure and growth checks. With one kidney, long-term monitoring for hypertension and growth is prudent. (Standard CAKUT care principles.) PMC
Developmental screening. Simple clinic tools (milestone checklists) determine whether motor and language development is on time.
B) Manual/bedside tests
Pupillary light reflex test. A penlight checks how the pupils react. In aniridia, the iris sphincter may be under-developed; reactions can be abnormal. JCI Insight
Visual acuity testing (age-appropriate). Teller cards/Lea symbols in infants; standard charts later. Baseline vision guides support and accommodations. JCI Insight
Cover–uncover and ocular motility tests. These simple maneuvers check for strabismus and how the eyes track targets. JCI Insight
Intercanthal distance measurement. A tape or calipers quantify telecanthus to document facial measurements over time. Genetic Diseases Info Center
C) Laboratory & pathological tests
Basic kidney labs. Serum creatinine/eGFR and electrolytes assess kidney function when one kidney is absent. (General CAKUT practice.) PMC
Urinalysis. Looks for protein, blood, or infection—common screens when structural kidney differences exist. PMC
Chromosomal microarray (CMA). First-line genetic test to detect 11p13 deletions (WAGR) and other CNVs that can explain the triad. ClinGen
Targeted gene testing for aniridia and ASD genes. Sequencing PAX6 first; if negative, consider FOXC1/PITX2 and other anterior-segment genes. NCBI+1
Kidney-development gene panel / exome. Includes HNF1B, PAX2, EYA1, SALL1, RET, GDNF, PBX1, etc., to look for a unifying diagnosis. PMC+1
D) Electrodiagnostic tests
Electroretinogram (ERG). Measures retinal function; helpful if vision seems worse than structural changes suggest. (Used in complex aniridia work-ups.) JCI Insight
Visual evoked potentials (VEP). Checks the visual pathway to the brain; useful when infants are too young for reliable acuity testing. JCI Insight
EEG (when indicated). If developmental delay comes with concerning spells or regression, EEG can screen for silent seizures; this is individualized.
E) Imaging tests
Slit-lamp biomicroscopy and intraocular pressure (IOP) measurement. Defines iris hypoplasia, cornea, and angle; screens for glaucoma. JCI Insight
Optical coherence tomography (OCT). Non-invasive imaging to confirm foveal hypoplasia often seen in aniridia, which explains reduced acuity. JCI Insight
Renal ultrasound. First-line imaging to confirm unilateral renal agenesis and check the remaining kidney’s structure. PMC
Brain MRI (case-by-case). If psychomotor delay is significant or atypical, MRI looks for structural brain differences that could change care plans.
Non-pharmacological treatments (therapies & others)
Below are safe, practical measures used by specialists. They aim to protect vision, preserve kidney health, and support development. Where evidence exists, I cite it.
Low-vision rehabilitation & assistive devices. Training in lighting, contrast, large-print, magnifiers, CCTV, screen readers can improve vision-related quality of life even if randomized evidence for global QoL is mixed. Cochrane Library+1
UV and glare control. Wide-brim hats, visors, photochromic/filtered lenses to reduce photophobia and protect ocular surface. Included in aniridia care roadmaps. PMC
Protective polycarbonate eyewear. Daily “safety” glasses reduce risk of injury to vision-limited or single-functional eyes; use polycarbonate lenses. American Academy of Ophthalmology+1
Moisture-chamber glasses & blink training. Reduce evaporative dryness and exposure symptoms on compromised corneal surfaces. (Endorsed within dry-eye stepwise care.) PMC
Lid hygiene & warm compresses. Supports tear film in meibomian dysfunction—part of TFOS DEWS-style first-line care. PMC

School-based accommodations. Large print, high-contrast materials, front-row seating, extra time; evidence supports function-level benefits in low-vision education. Cochrane Library
Hydration routine and “sick-day” kidney rules. Maintain fluids; pause nephrotoxic over-the-counter painkillers; seek care early for vomiting/UTI symptoms to protect a solitary kidney. PMC
Home blood-pressure (BP) checks. Catch early hypertension, which is a known risk in solitary-kidney states. infoKID
Sodium awareness. Practical cooking changes and label reading to keep salt reasonable when advised by nephrology. NIDDK

Psychosocial support. Vision loss and chronic monitoring can be stressful; counseling improves coping. (General low-vision rehab guidance.) Cochrane Library
Care coordination (“medical home”). A pediatrician/GP plus ophthalmology and nephrology ensure tests and referrals happen on time. (Reflected across solitary-kidney and aniridia guidance.) PMC
Drug treatments
There is no syndrome-specific drug proven for Sommer–Rathbun–Battles/ARAPR. Medicines are used to treat components (ocular surface disease, congenital glaucoma, hypertension/UTIs if they occur). Exact doses must be individualized by your clinician, especially in infants/children and in anyone with a single kidney. The classes below reflect common options and the evidence behind them.
Ocular surface / aniridia-associated keratopathy (AAK) & dry-eye–type symptoms
Preservative-free artificial tears (various polymers). Purpose: lubricate/restore tear film; Mechanism: increase tear volume & residence time. Evidence supports symptom improvement within weeks. Caution: use PF formulas for frequent use. PMC
Topical cyclosporine (various formulations). Purpose: steroid-sparing anti-inflammatory for chronic surface disease; Mechanism: calcineurin inhibition reduces T-cell–mediated inflammation; multiple RCTs support benefit. Note: Pediatric safety demonstrated in vernal keratoconjunctivitis contexts. JAMA Network+2PMC+2
Lifitegrast 5% ophthalmic. Purpose: reduce inflammatory dry-eye symptoms; Mechanism: LFA-1/ICAM-1 blockade; RCTs show symptom benefit vs placebo/CMC. PubMed+1
Short courses of topical corticosteroids (by specialist). Purpose: calm flares on the ocular surface; Mechanism: broad anti-inflammatory; Caution: raise IOP and infection risk—specialist-directed only, especially with glaucoma risk. (Standard dry-eye/ocular surface practice.) PMC
Autologous serum tears (specialty preparation). Purpose: provide epitheliotrophic growth factors; Mechanism: serum components mimic tears; evidence low-to-moderate and mixed; consider in refractory disease. PMC+1
Congenital glaucoma (often needs surgery first—meds are usually adjuncts)
Topical beta-blockers (e.g., timolol). Purpose: lower IOP; Mechanism: reduce aqueous production. Timolol is commonly first-choice in pediatric glaucoma, used as adjunct to surgery. Caution: systemic effects in infants; specialist dosing. EyeWiki
Topical carbonic anhydrase inhibitors (dorzolamide/brinzolamide). Purpose: lower IOP; Mechanism: inhibit aqueous humor production; often paired with timolol. EyeWiki
Oral acetazolamide (short-term bridge). Purpose: temporary IOP reduction pre-/post-op; Mechanism: systemic CAI. Caution: dosing adjustments & monitoring in children. NCBI
Prostaglandin analogs (latanoprost, etc.). Purpose: increase uveoscleral outflow; Note: limited efficacy in classic primary congenital glaucoma; used case-by-case. American Academy of Ophthalmology
Miotics (pilocarpine). Usually limited utility in congenital glaucoma; occasionally used after angle surgery. American Academy of Ophthalmology
Kidney-related when indicated (for solitary kidney with complications)
ACE inhibitors/ARBs (e.g., enalapril, losartan). Purpose: treat hypertension and reduce proteinuria to protect kidney; Mechanism: RAAS blockade. Used only if BP/proteinuria present under nephrology care. PMC
Antibiotics for UTIs (as needed). Purpose: promptly treat infections that could threaten the single kidney. Mechanism/choice: standard pediatric UTI protocols. PMC
Vitamin D ± phosphate binders (only if CKD-mineral bone disorder emerges). Purpose: correct CKD-related abnormalities; Mechanism: endocrine/mineral effects. Not routine in a healthy solitary kidney. AJKD
Other eye-related adjuncts (specialist-guided)
Antihistamine/mast-cell stabilizer drops if allergic surface disease worsens keratopathy symptoms. PMC
Topical antibiotics (short courses) if epithelial defects are infected or at high risk, per cornea specialist. (Standard corneal care.) PMC
Hypertonic saline ointment/drops for epithelial edema/erosions in selected cases. (Cornea practice pearls.) PMC
Lubricating gel at night to protect exposed cornea/poor blink. PMC
Cycloplegics (briefly) for ciliary spasm pain in corneal injury episodes, as directed. (Cornea practice.) PMC
IOP-safe anti-inflammatories under glaucoma/ cornea supervision when both conditions coexist. EyeWiki
Post-surgical IOP/anti-infective regimens (short courses) after goniotomy/trabeculotomy or corneal procedures—specialist-directed. Frontiers
Important safety note: Because this is a rare, pediatric-leaning constellation and sometimes involves a single kidney, I’m not listing doses or “times to take” online. Those details are individualized and must come from your treating clinicians. This keeps you safe and aligned with current pediatric ophthalmology and nephrology practice. NCBI+1
Dietary molecular supplements
Supplements do not treat ARAPR itself. A few may support ocular surface comfort or general health; evidence ranges from mixed to low-moderate.
Omega-3 fatty acids (EPA/DHA). May modestly improve dry-eye symptoms/signs in some studies; overall results mixed. Mechanism: anti-inflammatory lipid mediators. Cochrane Library+2PubMed+2
Vitamin A (only if deficient). Essential for ocular surface; deficiency causes xerophthalmia; supplementation reverses deficiency—not for routine use if levels normal. NCBI
Vitamin D (only if CKD-related issues arise). Bone/mineral support in CKD; not routine in healthy solitary kidney. AJKD
Lubricant gel-based formulations (carbomer/HA) at night. Not a nutrient but “molecular” tear film support improving symptoms. PMC
Flaxseed (ALA omega-3). Evidence less consistent than fish-oil (EPA/DHA); may help some patients’ symptoms. Cochrane
Balanced electrolyte hydration (oral rehydration approach during illness). Protects the single kidney from pre-renal hits. PMC
Antioxidant-rich foods (berries/leafy greens). General ocular surface and cardiovascular support; not disease-specific. (Lifestyle guidance within dry-eye/aniridia care.) PMC
Avoidance of high-dose vitamin A or D without testing. Fat-soluble vitamins can harm liver/kidneys if unnecessary. (General pediatric nephrology safety) AJKD
Iodized salt within advised limits. Supports thyroid/overall health while honoring nephrology sodium targets. NIDDK
Dietitian-guided protein planning. “Enough but not excessive” protein supports growth without stressing a solitary kidney. AJKD
Immunity-booster / regenerative / stem-cell therapies
There are no immune boosters or stem-cell drugs proven to alter ARAPR. Regenerative approaches focus on the cornea when aniridia-associated keratopathy (AAK) causes limbal stem-cell deficiency (LSCD).
Cultivated Limbal Epithelial Transplantation (CLET). Lab-grown corneal epithelial cells replace deficient limbal cells; can stabilize the surface, though long-term success varies and rejection is a risk (allografts need immunosuppression). EyeWiki+1
Simple Limbal Epithelial Transplantation (SLET). Small limbal fragments placed on the cornea with scaffold; mechanism is repopulation of epithelium; outcomes promising in LSCD generally, but aniridia is a tougher indication. PubMed+1
Amniotic membrane–assisted surface reconstruction. Biologic scaffold that supports healing; often combined with limbal procedures. Annals of Eye Science
Corneal transplantation (“triple procedures”). Used when scarring is advanced; in aniridia, grafts frequently fail without addressing LSCD first. MDPI+1
PAX6-targeted gene therapy (research stage). Animal and cellular models show promise, but human trials to date have not established clinical benefit (e.g., ataluren study didn’t meet its primary endpoint). PMC+1
Medical reversal of early limbal niche dysfunction. In selected LSCD linked to inflammation, early medical therapy may partly reverse signs without surgery. Turkish Journal of Ophthalmology
Surgeries
Goniotomy / trabeculotomy for congenital glaucoma. Why: first-line to open aqueous outflow and lower pressure early in life; medications are usually adjuncts. Frontiers+1
Medial canthopexy / trans-nasal wiring for significant telecanthus. Why: correct tendon laxity/malposition, improve cosmesis and function (tearing/cover). EyeWiki+1
Limbal stem-cell transplantation (CLET/SLET) for advanced AAK with LSCD. Why: restore a stable, epithelialized corneal surface before/without a graft. EyeWiki
Penetrating or lamellar keratoplasty ± “triple” procedure when scarring/cataract severely limit vision (often after stabilizing the surface). Why: improve optical clarity; recognize higher failure risk in aniridia. MDPI
Cataract extraction with IOL (when cataract is visually significant). Why: improve acuity; technically challenging in aniridia—done by experienced surgeons. PMC
Prevention tips
Wear polycarbonate protective eyewear daily (and for sports). American Academy of Ophthalmology
Use UV-blocking lenses/hat outdoors. PMC
Keep artificial tears on a regular schedule if advised. PMC
No NSAIDs (e.g., ibuprofen/naproxen) without nephrology guidance—protect the solitary kidney. PMC
Hydrate, especially during illness; seek care early for vomiting/fever. PMC
Check BP at least annually (often more) per nephrology/primary care. cdn.wchn.sa.gov.au
Keep vaccinations up-to-date; infections can threaten vision/kidney health. (General pediatric guidance embedded in care pathways.) PMC
Moderate salt intake if advised for BP. NIDDK
Maintain healthy weight & activity; most sports allowed with common-sense protection. PMC
Regular specialist follow-ups (ophthalmology + nephrology). PMC

Limit/avoid:
High-salt packaged foods (chips, instant noodles). NIDDK
Excess protein supplements or very high-protein diets. AJKD
NSAIDs unless your clinician says it’s safe. PMC
Energy drinks and sugary beverages. AJKD
Smoking exposure/vaping (ocular & kidney vascular harm). AJKD
Unregulated “kidney cleanses” or mega-vitamins (A, D) without labs. AJKD
Contact sports without appropriate protective gear. PMC
Poor sleep & skipped medications/tears. PMC
Eye rubbing (worsens surface disease). PMC
Delays in care for eye pain/redness or UTI symptoms. PMC
When to see a doctor
Eye red flags: sudden eye pain, vision drop, halos, light sensitivity, tearing, a whitened spot on the cornea—risk of glaucoma crisis or corneal breakdown. EyeWiki
Kidney red flags: fever with back/flank pain or painful urination (possible UTI), swelling, headaches or nosebleeds with high BP, reduced urine, or dark/frothy urine. PMC
Development: regression of milestones or concerning delays—early therapy helps most when started promptly. Genetic Diseases Info Center
Frequently asked questions
Is there a definitive genetic test for this exact syndrome? No; testing helps exclude other aniridia syndromes (e.g., PAX6/WAGR) but ARAPR has no proven gene. GeneVision
Can vision be normal? Some affected people have useful vision, but risks include keratopathy, glaucoma, and cataract; proactive care helps preserve function. BioMed Central
Does congenital glaucoma always need surgery? Often yes; goniotomy/trabeculotomy are first-line, with drops as adjuncts. Frontiers
Can the cornea be “fixed” with a transplant? In aniridia, corneal grafts often fail unless LSCD is addressed first (e.g., with CLET/SLET). WAGR Syndrome Association
Are there stem-cell cures? Limbal stem-cell procedures can stabilize the surface in some cases; results vary, and rejection is a risk with allografts. EyeWiki
Any gene therapy available now? Research is active; no approved therapy yet, and prior trials haven’t shown definitive benefit. PMC
Is one kidney enough? Usually yes—with lifelong monitoring for BP, proteinuria, and kidney function. PMC
Can children play sports? Generally yes; non-contact sports are fine; individualized advice and protective gear for contact/collision sports. PMC
Diet rules for one kidney? Balanced diet; avoid high salt and extreme high-protein unless advised otherwise; involve a dietitian. AJKD
Are omega-3 capsules helpful for the eyes? They may help symptoms for some, but evidence is mixed; safe when used appropriately. Cochrane Library
