Special features of tessellated fundus include RPE atrophy, choroidal segmentation and large surface area of retinal thinning.
Among 60 patients, 30 patients had tessellated fundus (Fig: 1), 30 patients had non-tessellated fundus.
Very severe NPDR, Early PDR and high risk PDR was 100% absent in tessellated fundus, but was 100% present in non-tessellated fundus (Table 1).
The correlation between tessellated fundus in the severity and duration of DR; 'p' value was 0.
The hypothesis is that low end arteriolar pressure (9) in tessellated fundus due to a low ocular perfusion pressure is a common denominator for the protective factor in DR.
Incidence of proliferative DR in tessellated fundus is low compared to non-tessellated/Hyperopic fundus.
