[Helicoidal peripapillary chorioretinal degeneration (HCPD)]

Area of Science:

• Ophthalmology
• Medical Retina Research
• Retinal Degeneration Studies

Background:

• Helicoidal peripapillary chorioretinal degeneration (HCPD) is a rare condition.
• It presents as bilateral, wing-shaped atrophic areas in the retina radiating from the optic disc.

Observation:

• Two cases of HCPD in women aged 23 and 58 were studied.
• A two-year follow-up period was conducted for both patients.

Findings:

• No significant changes were observed in the eye fundus of either patient.
• Electroretinography (ERG), electrooculography (EOG), and visual field evaluations remained stable.
• This indicates a potential lack of progression in these specific HCPD cases.

Implications:

• The findings suggest that HCPD may exhibit a stable or slowly progressing course in some individuals.
• Further research is needed to understand the natural history and long-term prognosis of HCPD.
• These observations contribute to the limited knowledge base on this rare retinal degeneration.
