    This section provides diagnostic services to the Centre which include Clinical pathology (including blood and urine sample collection), Histopathology and Cytopathology.  It performs on an average 36,000 investigations per year.  There is an ocular pathology museum, teaching and training programme in ocular pathology is also being provided for other medical colleges and hospitals in India.

Extensive work on orbital, intraocular tumors & eyelid tumors is being done.The department has also organized first  Ocular pathology workshop under the Indian Association of Ocular Pathologist on 25th March, 2006.

 A.  Services provided by the ocular pathology section.

 (I)     Histopathology & Frozen section :

      Diagnostic histopathology of ocular specimens received from operation theatre include corneal buttons, orbital, ocular tissues and trabeculectomy specimens.  In addition frozen section guided excision of lid tumors and frozen section for various histochemical stains is also done.                 

   

 Cryostat machine for rapid per operative diagnosis and fat stains 

    

 Well differentiated Retinoblastoma (Haematoxylin & Eosin Stain)

 

 (II)  Cytopathology:

 

      i.     Impression Cytology:  Done for diagnosis  of  dry eye,  corneal ,  conjunctival neoplasias,ulcerative eye lid lesions. 

  

 PAS Stain  (Goblet cells)

 

       ii.   FNAC (Fine needle aspiration cytology):  Being done for pre-operative diagnosis of palpable orbital, eyelid lesion and enlarged lymph node.                                             

     

Sebaceous gland Carcinoma

 (Papanicolaou stain )  

 

 

 Metastatic adenocarcinoma  (MGG stsin)  

         (III)  Clinical Pathology:

 a)     Blood investigation  by Auto analyzer.

  Hemogram – TLC-Total Leukocyte count.

                       DLC-Differential Leukocyte count.

               ESR- Erythrocyte Sedimentation Rate.

                Platelet count.

                Peripheral smear. 

 Autoanalyser

 

           b)    Urine analysis – Routine examination including urine for-

                   Protein 

                   Sugar

                   Microscopy.

 c)      Blood sample collection for all tests done at        Dr.  R. P. Centre laboratories.

 (IV)        Immunohistochemistry:   

Being done routinely for both diagnostic and research purposes.

        

Vimentin For Mesenchymal lesions

 

         

p53 tumor suppressor  gene in Rb. 

       

Museum:

 Interesting cases of lid, orbital lesion, intra ocular tumor,  preserved for teaching

 purpose.
