Retinitis Pigmentosa | Genetics, Pathophysiology, Signs & Symptoms, Diagnosis, Treatment

The video tutorial covers retinitis pigmentosa, a group of hereditary eye conditions causing degeneration of photoreceptors, primarily rods, leading to vision loss. It discusses genetic transmission modes, including autosomal recessive, dominant, and X-linked. The pathophysiology involves genetic mutations causing apoptosis in retinal cells. Symptoms include night blindness, tunnel vision, and photopsia. Diagnosis is through ophthalmological exams, and treatment is supportive, with some vitamin supplementation.
