Posterior form sympathetic ophthalmia.

Area of Science:

• Ophthalmology
• Immunology
• Pathology

Background:

• Sympathetic ophthalmia is a rare, bilateral granulomatous inflammation of the uveal tract following ocular trauma or surgery.
• Posterior form sympathetic ophthalmia (PSO) specifically affects the choroid and retina, often without anterior segment inflammation.
• Histopathologic distinctions and clinical management differences between PSO and classical sympathetic ophthalmia (SO) remain debated in the literature.

Purpose of the Study:

• To present two cases of posterior form sympathetic ophthalmia.
• To describe the histologic abnormalities observed in one case of PSO.
• To compare the histopathology, therapy, and prognosis of PSO with classical SO.

Main Methods:

• Clinical presentation and management of two patients with PSO were documented.
• Histopathologic examination of ocular tissues from one patient with PSO was performed.
• Literature review of previously reported cases of PSO and SO was conducted.

Main Results:

• Histologic abnormalities in the presented PSO case were described.
• No significant histopathologic differences were found between PSO and classical SO, apart from the absence of anterior uveal tract involvement in PSO.
• Therapeutic approaches and prognostic outcomes for PSO were found to be similar to those for classical SO.

Conclusions:

• Posterior form sympathetic ophthalmia is histopathologically indistinguishable from classical sympathetic ophthalmia, excluding anterior segment involvement.
• The clinical management and expected outcomes for PSO are comparable to those of classical SO.
• These findings suggest a unified understanding of sympathetic ophthalmia, regardless of the specific segment primarily affected.
