This study reports a rare genetic disorder causing retinal degeneration and lens subluxation in two brothers. The condition, inherited in an autosomal recessive manner, affects vision from early life.

Area of Science:

  • Ophthalmology
  • Medical Genetics

Background:

  • Two brothers presented with early-onset visual impairment.
  • Systemic examination ruled out Marfan syndrome and homocystinuria.

Observation:

  • Ocular findings included nystagmus, myopia, inferior lens dislocation, and posterior subcapsular opacities.
  • Fundus examination revealed attenuated retinal vessels, macular atrophy with pigment clumping, and perivascular sleeves.
  • Electroretinography showed reduced photopic and scotopic responses, with visual field constriction.

Findings:

  • This family presents a unique combination of retinal degeneration and bilateral lens subluxation.
  • The condition appears to be inherited in an autosomal recessive pattern.

Implications:

  • This case expands the spectrum of inherited retinal degenerations.
  • Further research into the genetic basis of this disorder is warranted.
  • Understanding this condition can aid in early diagnosis and management of affected families.
