Retinal Detachment

In rhegmatogenous retinal detachment, which of the following is the MOST common predisposing factor in a non-myopic, non-traumatized eye?

A 58-year-old man from Mumbai presents with sudden onset of floaters and photopsia in his right eye for 2 days. He is highly myopic (−8 D) and has a history of lattice degeneration. On examination, visual acuity is 6/60 in the right eye. Fundoscopy reveals a superior temporal retinal detachment with a single horseshoe tear. The macula is still attached. What is the most appropriate immediate management?

A 72-year-old woman from Delhi with a history of cataract surgery 3 years ago presents with gradual onset of floaters and a shadow in the inferior nasal field of her left eye over 1 week. She denies photopsia. Visual acuity is 6/18 in the left eye. On fundoscopy, a shallow retinal detachment is seen in the inferior nasal quadrant with a smooth, convex border and no visible retinal breaks. B-scan ultrasonography shows a thin, mobile membrane. What is the most likely diagnosis?

A 52-year-old woman with a history of cataract surgery 6 months ago presents with flashing lights and a shower of floaters. Examination reveals a C-shaped retinal detachment in the superior quadrants. Regarding the clinical features and management of retinal detachment, all of the following statements are correct EXCEPT:

A 42-year-old woman with a history of cataract surgery 6 months ago presents with progressive blurring of vision and a shadow in the temporal field of her right eye. She reports seeing occasional flashes of light 1 week ago but attributed them to stress. On examination, visual acuity is 6/12 in the right eye. Dilated fundoscopy shows a temporal retinal fold extending toward the optic disc, with the macula still attached but at the edge of the detachment. B-scan ultrasonography confirms a shallow detachment with a posterior break. What is the most likely risk factor for this detachment?
