Purpose:
To describe the clinical manifestations of classic pars planitis (CPP) in Mexican patients. We report here the most frequent complications, medical and surgical treatment, and visual prognosis.
Material And Methods:
A retrospective, descriptive case series examined the clinical features, complications, and treatment (medical and surgical) of CPP patients seen at the Inflammatory Eye Disease Clinic from January 1990 to September 1999.
Results:
One hundred and sixty patients met inclusion criteria for the study. Mean age at presentation was 10 years and males were more frequently affected. Both eyes were affected in 84.4% of the cases. The most frequent complaint was decreased visual acuity. Initial visual acuity (VA) ranged from no light perception to 20/20 (mean 20/50), and mean final VA was 20/30. The most frequent clinical manifestations were vitritis (99.7%), snowballs (99.3%), retinal vasculitis (89.2%), and snowbanks (63.1%). The most common complications were cystoid macular edema (63.4%) and cataract (47.5%). Periocular corticosteroids were used in 97.5% of cases, systemic corticosteroids in 68.1%, and other immunosuppressive drugs in 21.3%.
Conclusions:
CPP in the Mexican population is more frequent in males and usually presents in patients less than 14 years of age. It is typically bilateral, and the most common symptom is decreased visual acuity. The most important clinical findings are located in the vitreous and retina. Cataract and cystoid macular edema are the most frequent complications. Treatment comprises periocular and systemic corticosteroids or other immunosuppressive drugs.
Insights
Classic pars planitis (CPP) in Mexican males often presents bilaterally before age 14, with decreased vision being the main symptom. Vitreous and retinal findings, along with cataract and cystoid macular edema, are common.
Area of Science:
- Ophthalmology
- Immunology
Background:
- Classic pars planitis (CPP) is an inflammatory eye condition.
- Understanding its clinical profile in diverse populations is crucial for effective management.
Purpose of the Study:
- To delineate the clinical manifestations, complications, and treatment outcomes of CPP in Mexican patients.
- To identify demographic and clinical patterns specific to this population.
Main Methods:
- A retrospective descriptive case series.
- Analysis of clinical features, complications, and treatments of 160 CPP patients over a decade (1990-1999).
Main Results:
- CPP predominantly affected males, with a mean age of 10 years; 84.4% had bilateral involvement.
- Common manifestations included vitritis, snowballs, retinal vasculitis, and snowbanks.
- Cystoid macular edema (63.4%) and cataract (47.5%) were the most frequent complications, with mean final visual acuity of 20/30.
Conclusions:
- CPP in Mexico is characterized by early onset (under 14), male predominance, and bilateral presentation.
- Vitreous and retinal involvement are key features, with cataract and CME being significant complications.
- Treatment primarily involves periocular/systemic corticosteroids and other immunosuppressants.
