                  Reports Second Quarter 2004 Financial Results

     - Eyetech files new drug application for Macugen(TM)(pegaptanib sodium
               injection) and accelerates pre-launch activities -


New York, NY - July 23, 2004 - Eyetech Pharmaceuticals, Inc. (Nasdaq: EYET), a
biopharmaceutical company that specializes in the development and
commercialization of novel therapeutics to treat diseases of the eye, today
reported its consolidated financial results for the three months ended June 30,
2004.

Second Quarter 2004 Financial Highlights
- ----------------------------------------

     o    Collaboration revenues of $12.5 million for the second quarter 2004
          compared to $11.2 million for the same period in 2003. Collaboration
          revenues for the half-year period ended June 30, 2004 were $24.3
          million compared to $18.5 million for the same period in 2003.

     o    Operating loss of $31.9 million for the second quarter 2004 compared
          to an operating loss of $10.1 million for the same period in 2003. For
          the half-year period ended June 30, 2004, the operating loss was $47.5
          million compared to $16.0 for the same period in 2003. The increased
          operating loss reflects milestone payments, acceleration of pre-launch
          activities for Macugen for the treatment of the wet form of
          age-related macular degeneration (AMD) and completion of a secondary
          offering on behalf of stockholders.




          Second quarter results do not include a milestone payment from our
          partner, Pfizer Inc., which is payable to us upon acceptance for
          review by the Food and Drug Administration (FDA) of our complete new
          drug application (NDA) filing for Macugen.

     o    Research and development expenses for the second quarter were $33.9
          million in 2004 compared to $19.7 million for the same period in 2003.
          The principal reason for this increase was $9.2 million of milestone
          payments to Gilead Sciences, Inc., Nektar Therapeutics and Isis
          Pharmaceuticals, Inc. related to the completed submission of our NDA
          for Macugen and an initial payment to Archemix Corp. in connection
          with our research and development collaboration. In addition, as a
          result of the early submission of our NDA filing for Macugen, we
          incurred approximately $4.4 million of development expenses in
          connection with our acceleration of pre-launch activities for Macugen,
          specifically for pre-approval inspection readiness and raw material
          purchases.

     o    Sales and marketing expenses for the second quarter were $6.2 million
          in 2004 compared to $0.7 million in the same period in 2003. This
          increase is primarily due to the accelerated hiring of a sales force.

     o    General and administrative expenses for the second quarter were $4.3
          million in 2004 compared to $0.8 million in the same period in 2003.
          This increase is primarily due to $1.0 million of costs incurred in
          connection with our secondary offering, $1.5 million for the write
          down of our lease on our former corporate offices in New York and
          increased administrative and facility costs.

     o    Net loss attributable to common stockholders for the second quarter
          was $31.0 million in 2004 compared to $11.3 million for the same
          period in 2003. Basic and diluted net loss per common share in the
          second quarter was $0.77 in 2004, compared to $2.88 for the same
          period in 2003. Pro forma basic and diluted loss per common share in
          the second quarter was $0.77 in 2004, compared to $0.40 for the same
          period in 2003. Net loss attributable to common stockholders for the
          half-year period ended June 30, was $46.8 million in 2004 compared to
          $19.0 million for the same period in 2003. Basic and diluted net loss
          per common share for the half-year period ended June 30, was $1.38 in
          2004,


          compared to $4.94 for the same period in 2003. Pro forma basic and
          diluted loss per common share for the half-year period ended June 30,
          was $1.23 in 2004, compared to $0.69 for the same period in 2003. The
          pro forma basic and diluted loss per common share gives effect to the
          automatic conversion of our outstanding convertible preferred stock
          into shares of common stock upon completion of our initial public
          offering in February 2004.

     o    $253.2 million in cash, cash equivalents and marketable securities at
          June 30, 2004.

Commenting on Eyetech's achievements during the first half of 2004, Chief
Executive Officer and co-founder, David R. Guyer, M.D. stated, "We continue to
meet our objectives by completing, ahead of schedule, the filing of our NDA for
the use of Macugen in the treatment of wet AMD. We look forward to our meeting
with the public advisory committee of the FDA on August 27, 2004 and are working
to bring Macugen to patients in 2005."

Second Quarter 2004 Operations Highlights
- -----------------------------------------

     o    Completed the filing of our NDA with the FDA for Macugen in the second
          quarter of 2004.

     o    The FDA announced the meeting of a public advisory committee of the
          FDA to discuss our NDA for the use of Macugen (pegaptanib sodium
          injection) for the treatment of wet AMD (21-756, pegaptanib sodium
          injection (proposed trade name, Macugen)) to be held on August 27,
          2004.

     o    Released data from a Phase 2 study of Macugen which showed positive
          visual and anatomical outcomes in the treatment of diabetic macular
          edema (DME). Diabetic retinopathy is the leading cause of blindness in
          people less than 50 years of age in developed countries. DME is the
          leading cause of vision loss in diabetic retinopathy.

     o    Completed a secondary public offering of 4,439,000 shares of common
          stock in the second quarter 2004. All of the shares were sold by
          selling stockholders at $38.50 per



          share. Eyetech did not issue any primary shares in, or receive any
          proceeds from, the offering.

     o    Completed the recruitment of 43 regional sales representatives and 5
          regional sales managers in anticipation of our planned launch of
          Macugen.

     o    Appointed two new independent board members, Phillip M. Satow, former
          pharmaceutical executive from Forest Laboratories, Inc. and Pfizer
          Inc., and Michael J. Regan, former Vice Chairman and the Chief
          Administrative Officer of KPMG LLP.
