In this paper,we introduce a three-step composite implicit iteration process for approximating the common fixed point of three uniformly continuous and asymptotically generalizedΦ-hemicontractive mappings in the intermediate *** prove that our proposed iteration process converges to the common fixed point of three finite family of asymptotically generalizedΦ-hemicontractive mappings in the intermediate *** results extends,improves and complements several known results in literature.

The study investigated the burden and severity of depression in relationship with visual impairment in Nigeria. Four hundred (400) male and female in and outpatients with various degrees of visual impairment attending a clinic in the department of ophthalmology, Enugu State University Teaching Hospital, Parklane Enugu were used. They were selected through the purposive sampling method. The socio-demographic questionnaire, Beck depression inventory and WHO-VFQ (visual function questionnaire were used to collect data. The result showed that the domains of vision-related health status were negatively related to depression at (-0.4) also general vision (-0.09), ocular pain (-0.23), vision-specific mental health (-0.03), role difficulties (-0.03), role difficulties (-0.03), dependency (-0.09), color vision (-0.30) and peripheral vision (-0.13) and vision-specific social functioning. Domains of near acuity and vision specific social functioning were positively related, but the only statistically significant domain was vision-specific social functioning at (0.30, p 0.001). It was suggested that hospitals, families and other social groups should ensure that they provide social and emotional support to the visually impaired using their facilities.
